Removing chaos from confusion: assigning names to common human and animal pathogens in .

The genus encompasses highly prevalent and aggressive human and animal fungal pathogens. Here we assign formal descriptions and Latin binomials to some of the most clinically relevant phylogenetic species of the genus. Three new species, named , and (previously assigned to the informal names '' species complex (FSSC) lineages, FSSC 43, FSSC 7 and FSSC 20, respectively) are described on the basis of multilocus phylogenetic analyses (using , ITS, LSU and loci) and morphological characters. Lineage FSSC 9 is conspecific with the ex-type strain of , thus the new combination is proposed. In addition, and based on the latest taxonomy for this generic complex, new combinations are introduced for four medically important taxa, , and . The most significant distinctive features for all the clinically relevant species treated here are compared and illustrated.
